Description

Getting the following error when using Swift plugin

✗  Can’t convert color {"$value":{"colorSpace":"srgb","components":[0,0,0],"alpha":1},"originalValue":"rgba(0,0,0)","source":{"loc":"file:///Users/kovalju/Documents/Projects/tokens/tokens/base/color.json"}} to Culori color

Here's my config:

import { defineConfig } from "@terrazzo/cli";
import css from "@terrazzo/plugin-css";
import sass from "@terrazzo/plugin-sass";
import swift from "@terrazzo/plugin-swift"

export default defineConfig({
  tokens: [
    './tokens/base/animation.json',
    './tokens/base/breakpoint.json',
   ...
  ],
  outDir: './dist/key',
  plugins: [
    css({
      modeSelectors: [
        {
          mode: "light",
          selectors: [
            '[data-mode="light"]',
          ],
        },
        {
          mode: "dark",
          selectors: [
            '[data-mode="dark"]',
          ],
        },
      ],
    }),

    sass({
      filename: "index.scss",
    }),

    swift({
      catalogName: "Tokens",
    }),
  ],
  lint: {
    /** @see https://terrazzo.app/docs/cli/lint */
    rules: {
      "core/consistent-naming": ["error", { format: "kebab-case" }],
    }
  },
});

Token file

{
  "color": {
    "black": {
      "$type": "color",
      "$value": "rgba(0,0,0)"
    },

      "$type": "color",
      "$value": "rgba(255, 255, 255)"
    },
    "transparent": {
      "black-20": {
        "$type": "color",
        "$value": "rgba(0, 0, 0, .2)"
      },
      "white-10": {
        "$type": "color",
        "$value": "rgba(255, 255, 255, .2)"
      },

Thanks for reporting! The Swift plugin is not really in a great state at the moment. If you’ve worked with tokens in Swift before, do you have any thoughts about the overall design patterns? Would there be a more usable one instead? Would love to talk more about what would be useful for your usecase (and we can either go with a different approach, or simply fix up the current one)

Also, just re-released the plugin to npm, which may have been stale. Give it a try with 0.0.2 and the latest version of @terrazzo/cli again to see if you have the same error

Thank you I'll check it out. No I don't have much experience with Swift but something our DS will have to support soon.
